ABANDONED. YA Murder/Mystery Novel with Multiple Stories; general gist of all of them being a group of kids are trapped somewhere or lost and are being killed off one by one

[That_one_band_kid]

I read this book back in 2014-2015 that was fairly new and it had multiple stories in it, the general gist of all of them being a group of kids are trapped somewhere or lost and are being killed off one by one and the others are trying to figure out who the murderer is. Some romantic subplot. There are multiple books, but I remember that in one they are snowed in a mall, another flooded in a cabin and another they're locked in a store. The cover has an eye on it and has only 1-2 words as the title. Books are kinda long. Hopefully, someone can help me find it it's been driving me crazy. Thank you!!!

Are the various stories connected, with the same kids? Or is each story totally independent of the others? When you say "There are multiple books" do you mean that his was series, where each book had lots of stories in it or each book was a single story?

Maybe One of Us Is Lying, or Five Total Strangers?
